When should insulation inspection be called in a building project?

Insulation inspection should be called before boarding because this is the stage when the insulation materials are exposed and accessible for inspection. Inspecting the insulation at this point ensures that it has been installed correctly, meets building code requirements, and performs effectively for thermal efficiency.

Once the boarding — such as drywall or sheathing — is installed, the insulation becomes covered and inaccessible, making it impossible to verify its proper installation without removing the finished material. Addressing any issues with insulation before boarding helps to prevent potential problems related to energy efficiency, moisture control, and overall comfort within the building. By conducting the inspection at this critical juncture, builders can ensure compliance and quality before moving on to the next stages of construction.
